HMD Kontro LMV-801S Vertical Low-Flow API 685 Pump

HMD Kontro LMV-801S Vertical Low-Flow API 685 Pump

Specifically for Low-Flow Duties

The LMV-801S combines the Sundyne Barske Wheel hydraulics with the HMD Kontro magnetic drive pump technology, providing a safe, reliable and efficient sealless pump solution for low-flow pump applications. It is built to comply with both the API 685 and API 610 standards and is engineered to eliminate product emissions and improve plant personnel safety, whilst delivering optimised low-flow performance with the time-proven Sundyne direct drive hydraulics.

The LMV-801S is dimensionally interchangeable with the traditional mechanically sealed LMV-801, and can be easily dropped into existing pipework – making this sealless upgrade possible without the need to modify piping and foundation layouts. Additionally, a plug-in version of the pump is available, enabling customers to swap out the mechanical seal drive end with the new sealless option without disconnecting the existing LMV-801 casing and diffuser from the piping.

Key Design Features:
• Barske Wheel hydraulics for optimum efficiency at low flows.
Compact vertical in-line design configuration.
• Directly interchangeable with the Sundyne LMV-801 providing an easy sealless upgrade path for existing installations in difficult-to-seal pump applications.
Fully compliant to the API 685 sealless centrifugal pump standard.
Total product containment with no leaks or emissions, improving operator safety and environmental protection.
No seals or seal support systems to maintain, reducing overall lifecycle costs.
Easy to install, commission, operate and maintain, with no requirement for special tools.
